- If the patients at the NSU clinic have these exclusion criteria documented in their medical chart, they will not be approached for recruitment in the study. During the verbal pre-screening, the research assistant will ask the subject if they have any of the above conditions. If so, they will not be eligible to participate in the study. The same verbal pre-screening will be used at the yoga studio for recruitment. No data will be collected for subjects who are excluded during the pre-screening.
